Aluminum panels are often manufactured into sound barriers for lightweight, excellent corrosive resistance and self-support. Aluminum sound barriers are not only used in traffic areas but also factories and workshops where machines make serious noise pollution.

As an absorptive sound barrier, aluminum panel are designed with various hole patterns such as dotted or slits. To maximize sound absorptive performance, fillings are required such as EPDM, fiber glass and aluminum foam.

Many sound barriers make full use of advantages of clear noise barrier and aluminum barrier which can absorb noise and also provide support frame to polycarbonate or acrylic sheets. This sound barrier system will not obstruct light transmission while reducing noise level at utmost.
